I did an argyle afghan in crochet and couldn't have survived without bobbins. I always considered it intarsia, but I'm no expert!!!! You can see my afghan under the crochet section. I would include a link here, but I don't know how!!

I did the same thing. I stranded my major background color and used bobbins for all the rest. As it was I had about 40 bobbins hanging off at a time; if I hadn't stranded the background, who knows how many there would have been!
